MACHINE FOR STRETCI-IING AND DRYINGCLOTH.

Specification of LettersiPatent No. 8,563, dated December 2, 1851.

To altwhom t may concern.' i

` Be it known that I, THOMAS Barrows, of Dedham, in the county of Norfolk and State of Massachusetts, have invented a new `or Improved Machine for Stretching and Drying Cloth in the Piece; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures,rand references thereof.

Of the said drawings, Figure l, denotesfa top view of `my said machine. Fig. 2- isan elevation of one end of it. Fig. 3 is an elevation of the other end thereof. Fig. 4. is a side elevation. `Figq is a central,vertical and transverse section of it. Fig. 6 is an end view of` one of the widthwise rotary stretchers. Fig. 7 is a central and lonfritudinal section ofit (the stretcher). vFlg. 1

8 is an end viewof the shaft and cams, and slat holders ofthe widthwise stretching apparatus. i

` A, B, are two metallic cylinders arranged with their axes parallel to one another, and

supported by the framework H; such cylinders being so applied to such-framework as to be capable of being put in rotation around their respective axes.` Each of saidA cylinders has a spur gear wheel a. or fixed upon its shaft, which spur wheel engages with `a pinion c, or (Z, represented in dotted lines (in Fig. 2), and aliiXedsto the side of another spur gear e, or f, which turns on a stationary axle g or h.: One of the 'gear wheels viz, f `is made to engage with anjother spur gear lc, which turns on` a stationary axle z'; all these gears being arranged with respect to one another as seen i'n the drawings;

The driving shaft of the machine is represented at Z, and as having a pinion m, xed upon one end of it, and made to engage either with the wheel e or the wheel is, at pleasure, so as to impart a rotary movement to either one of the cylinders A, B, as the case may require. There isa fast `pulley 0, and a loose pulley p, applied to the other end of the driving shaft, a band from some suitable power, being made to operate around one or the other, and when upon the fast pulley, to impart rotary motion to the driving shaft. The journal of that end of the driving shaft, which is nearest to the pinion of the said shaft, is affixed upon a slide g, which is jointed to or so connected with a hand lever 1", turning on a fulcrum s, as to be capable of being moved by said hand lever, and so as to cause the pinion of the shaft to engage with one or the other of the spur gears o, or 7c, as circumstances may require.

Over the cylinders A, B, are three -or any other suitable number of steam drying cylinders, E, F, Gr, the three represented in the figure, being arranged with `respect to the rot-ating cylinders or beams A, B, and to certain widt-hwise rotary stretchers C, D, as seen in the drawings. Each of the rotary `stretchers being placed directly over one of `the cylinders A, B, andv for the purpose of lstretching t-he cloth widthwise. 'The rotary Astretcher will be hereinafter more particularly described.

Each drying cylinder E, F or G, is made to receive steam from a boiler through a conducting pipe I, which proceeds from the boiler, and has a series of branchk pipes S, T, U, V, whichlead the steam from it into `the hollow axles W, X, Y, of the `drying cylinders, and also into that (Z), of one of the cylinders A, Each `branch pipe is provided wit-h a stopcock a', b, c, or d, by which the steam may be let in or let off at pleasure.

Each of the widthwise rotary st-retchers is made in the following manner; that is to say, it consists of a horizontal shaft, having `four octagonal or other proper shaped heads e', j", g', it', fixed upon it, and two cylinders c; the periphery of each yof the said cylinders, has acircular grooveV Z', in andV around it, (as shown in Fig. 9), which is an external view of the shaft, its cylinders, and octagonal plates or heads. Fig. 10is an external side view of the widthwise stretching apparatus. The grooves of the periph eries of the cylinders of the shaft of the widthwise stretching apparatus are not made in planes which are respectively at right angles to the axles of the shaft,but are in planes, which each stand at an acute angle with the shaft. Each of these grooves receives a projection m', from one of the slats a, a', a', o', 0, 0, the said slats being supported (so as to be capable of being moved endwise) by the polygonal heads e', f, g', h. Two of these polygonal heads, viz, e', f', support one set of the slats on their polygonal sides; while the other two, support the other set in the same manner.v

Each slat of one set is arranged in a line of some one of the other set, and made to lap projections from the framework is to hold said heads stationary, during the rotation of the shaft and slats, and polygonal slat holders of the widthwise stretching apparat-us; the studs of the heads, as well as the projections from the framework, being so arranged as to bring the grooves of the heads into the right position to move two of the stretching slats (in line with oney another), atl their greatest distance apart when they are directly over` and nearest to, the cylinder or beam A, B, immediately under them.

The externalsurface of the slats of the stretching apparatus is to be made` rough or furnished with points teeth, or other suitable contrivances, such as will enable them to adhere to the surface of the cloth passing over them. 'l

The course of the piece of cloth is represented by a blue line at L in the drawing, one end of the cloth being fastened to one cylinder A or B, while the remainder of the cloth is carried between the said cylinder, and the widthwise stretchingy apparatus C or D, over it; thence under a guide roller M or N; thence over-and around the drying cylinder E or G, which is directly over said guide roller; thence down, underneath and nearly around the dryingcylinder-E; thence upward over and around the other upper drying cylinder; thence under the second guide roller; thence over and partially around the next widthwise stretching apparatus, and next Wound upon the cylinder or beam, under said last named widthwise stretching apparatus, the end of said piece being previously attached to the cylinder. Now by putting the other or first named cylinder or beam in motion, in the right direction, we draw the cloth away from the seci ond one, and wind it on the first, the cloth in the meantime, being stretched, not only E and lengthwise ywhich itl was previously unwound, it being understood that the several steam cylinders are in a heated state, in consequence of steam being admit-ted within them. The

cloth may be thus operated on as many times as maybe necessary to stretch it both lengthwise and widthwise, and to dry it, and to impart to it a luster and finish such as may be desirable and this without the necessity in the meantime (as is the case in other machines of the kind) of removing it and replacing it in the machine.

In order to increase the power of my improved mechanism, to stretch a piece of goods lengthwise I applyto each shaft of the main beams or cylinders A, B, a friction pulley s', or t', (see'Fig. 3) and afric- `tion yoke or brake u', or o', the said yoke being attached to a lever w, or which j turns upon a stationary pin or fulcrum (at one end), projecting from the main framework. On the other end of this lever, a weight y, is hung such as may bel sufricient to produce the necessary degree of 'pressure-of the friction brake upon its pulley.

What I claim as my invention is- The combination of the two winding stretching contrivances or stretchers, the two widthwise rotary stretchers C, D, and the three or any other suitable number of drying cylinders E, F, G, substantially as described, so as to enable a person to cause a piece of cloth to pass `in one direction over and around the drying cylinders, and next in the opposite direction, as many times as may be desirable, in order to stretch, dry and finish the same to the extent that may be required.

In testimony whereof I have hereto' set my signature this thirtieth day of July, A. D. 1851.

THOMAS BARROWS.
